Unsolved Problem Q809001



Uniform Boundedness Conjecture for Rational Points


Statement:

For a given number field \(K\) and a positive integer \(g\geq 2\) there exists a number \(N(K,g) \) depending only on \(K\) and \(g\) such that for any algebraic curve \(C\) defined over \(K\) having genus equal to \(g\) has at most \(N(K,g) \) \(K\)-rational points.



Partial Results:

Caporaso, Harris, and Mazur [1] showed that the conjecture is true under the assumption of the Bombieri-Land Conjecture.
